Multifunctional Display Module MOD 21

Multifunctional Display Module MOD 21

Display module for simultaneous operation of two encoders, absolute or incremental in any combination 8 control inputs and 16 control outputs, 40 cam switches

SSI-Interfaces

For operation of absolute single- or multiturn- encoders with resolution up to 30 bit with serial SSI-Interface.

Incremental-Inputs

For operation of incremental encoders with 3 or 6 output channels, RS422 line driver or push-pull outputs. Optically insulated with optocoupler.

Display-Scaling

Scale factor, adjustment values and counting direction are separatly programmable for both encoders.

Programmable Control-Inputs

8 optically insulated control-inputs are programmable for various functions, e.g. storing of display data or enable of counter.

Programmable Control-Outputs

16 optically insulated control-outputs, which can be programmed separately by 40 cam switches as a comparator, cam switch or pulse switch. The cycle time is only 500 µs.

Analogue-Output

1 optically insulated programmable analogue-output, which can be used as voltage or current output. High precision D/A-converter with 16 bit resolution. For data source of the analogue output position or velocity of one encoder can be selected.

Serial Interfaces

RS232C One display module can be connected to a PC for programming and reading data.
RS422/485 Up to 31 display modules can be connected to a PC.
CANBUS Up to 32 display modules can be connected with CANBUS.
